Estudio de cultivos celulares primarios derivados de Lucilia sericata (Diptera: Calliphoridae)

The main purpose of this study was to obtain primary cell cultures derived from Lucilia sericata (Diptera: Calliphoridae). Necrophagous this fly is used for determination of post-mortem interval and larval therapy. Since explants embryonated eggs were performed in various culture media (Grace Schneider, MM/VP12, DMEM, Grace/L-15 and L-15), supplemented with 20% fetal serum. Sterilization of the biological material was carried out by immersing it in formaldehyde and sodium hypochlorite solutions. The cell growth was initiated in the L-15, MM/VP12, and Schneider Grace/L-15 in an average time of 10 days after completion of planting by the proliferation of groups of colonies scattered on the surface of the boxes crops and also from the endings of larval fragments. The evolution of cell growth to the formation of monolayer semi-confluent was relatively fast, reaching at 3 weeks post-explant. Cellular morphology in cultured cells was heterogeneous, especially epithelioid forms, similar to nerve, giant and irregular. Comparison of the growth characteristics of these cell cultures with those obtained from other species of flies was more favorable in the evolution of those obtained from L. sericata, on the grounds that the cells are better adapted to the physical-chemical conditions of several culture media. This is the first report of a cell culture-fly family Calliphoridae.

Diseño de una estrategia de desarrollo responsable y sostenible de productividad estructurada en los soportes categóricos y enfoques productivos

El presente documento, tiene como finalidad presentar una estrategia de desarrollo responsable y sostenible social y ambientalmente, estructurada en cinco ejes categóricos y tres enfoques de la productividad, los cuales son determinados en el recorrido de la investigación.
